There are now over 40 PostNL Sorting Centers around the world. While the majority can be found in Europe, the Netherlands-based operation also has facilities in America, Australia, and partnerships in the Far East.
In this list, we have rounded up all the PostNL sorting center codes, alongside their locations.
First, let’s quickly cover what a PostNL Sorting Center is.
What is a PostNL Sorting Center?
A PostNL Sorting Center is a large warehouse where mail and packages are sorted for onward dispatch to their relevant destinations.
For example, a PostNL sorting center that opened in Tilburg, Netherlands in 2019 is 7,600 square meters in size and has the capability to sort 32,000 parcels a day.
A more recent announcement from PostNL states that an upcoming project based in Westzaan (also in the Netherlands) will be even larger with an expected sorting capability of 40,000 to 50,000 packages a day.
Essentially, the sorting center is a hub in the shipment infrastructure, where parcels arrive and are sorted so that they can then begin the next leg of the journey toward the area of delivery.
A package can pass through a PostNL sorting center both at the beginning of the shipment journey (after being initially received by the carrier) and at the end before being sorted for final delivery.

Where are your collection points in Accra-Ghana
Hello, I mailed a parcel from Luxembourg POST to Netherlands, with an incorrect address. And the parcel was stuck in Amsterdam International Mail Center for over 20 days according to my track&trace number.
I want you to help to return it to me and wonder when can you mail it back to Luxembourg.
Thank you very much!
Hello, I mailed a letter from Croatia post to Netherlands, to the address of Maastricht University. And the letter was stuck in Amsterdam International Mail Center on 09.06.2023. according to my track&trace number which is RG357677605HR.
As this documents are for my enrolment to Maastricht University it is very important for me. Can you please tell me when they will be delivered to Maastricht University.
Thank you very much!
Hi there, I would advise that you contact the university to double-check whether the documents have been receievd. The Croatia Post track and trace as well as Parcelsapp show the item as delivered. The fact that the “Amsterdam International Mail Center” alert is still showing is likely because the service that made the delivery provides unreliable updates. It seems to me that delivery took place, however, with it being so important, double-checking with the Uni is definitely recommeded. 🙂 Good luck with your studies.
